I saved the day !
The game is fun, it looks and sound good, controls well, the grazing for mana mechanics is a good implementation of the theme and is fun to deal with especially since the roster of enemies seems adapted to it, the speed of the character and bullets feel right, the different bullet patterns and enemy waves are good and the challenge feels right too.
The volume of the music almost feels slightly too low. Also I feel like the waves where the enemies all just stand there without moving feel a bit less dynamic, maybe because they are not animated (which is fine) either, but I don't know maybe it's just me. These are details anyway of course.
Solid entry, thanks for sharing.
